cgroup: fix broken css_has_online_children()
After running:
# mount -t cgroup cpu xxx /cgroup && mkdir /cgroup/sub && \
rmdir /cgroup/sub && umount /cgroup
I found the cgroup root still existed:
# cat /proc/cgroups
#subsys_name hierarchy num_cgroups enabled
cpuset 0 1 1
cpu 1 1 1
...
It turned out css_has_online_children() is broken.
